Answer:
4.08moles
Explanation:
The balanced equation of this reaction is given as:
H2SO4 + 2NaOH -> Na2SO4 + 2H2O
From the above balanced equation, 1 mole of H2SO4 is needed to react with 2 moles of NaOH.
Using the formula below to calculate the number of moles in 200g of H2SO4;
mole = mass/molar mass
Molar mass of H2SO4 = 1(2) + 32 + 16(4)
= 2 + 32 + 64
= 98g/mol
number of moles = 200g ÷ 98g/mol
n = 2.04mol
Since 1 mole of H2SO4 is needed to react with 2 moles of NaOH.
Then, 2.04mol of H2SO4 is needed to react with 2.04 × 2/1 = 4.08moles of NaOH.
Answer:
Wavelength, distance between corresponding points of two consecutive waves. ... Wavelength is usually denoted by the Greek letter lambda (λ); it is equal to the speed (v) of a wave train in a medium divided by its frequency (f): λ = v/f.
Explanation:
Paramecia are examples of unicellular organisms. They are protists.
<h3>Protists</h3>
Protists are eukaryotic unicellular (single-celled) organisms that do not fit into any other category.
Paramecia are protists microorganisms generally found in aquatic habitats (e.g., a pond).
Paramecia generally have an oblong shape and they are covered with tiny structures known as cilia (for motion).

thunderstorms and heavy rain
Explanation:
The weather in a region with an incoming air mass made up of moist air is predominantly that of thunderstorms and heavy rain.
Moist air brings in rainfall and thunderstorms. They are peculiar and predominant in tropical regions of the world .
- A moist air is an air mass that is moisture laden or full of water vapor.
- They are usually formed where evaporation of water vapor from sea water is very high.
- The evaporated water is warmer and lighter than the surrounding air.
- By virtue of this, it moves inland and condenses to form massive rainfall accompanied by thunderstorm.
